On one exemplary embodiment, the torqueretention arrangement can be used in a bolt and nut assembly tofacilitate in the torquing of the nut on the bolt. One non-limitingapplication is the use of the torque retention arrangement in theassembly of flange and pipe connections wherein the torque retentionarrangement is used in conjunction with flange bolt torquing of pipingsystems, and will be described with particular reference thereto.However, it is to be appreciated that the present exemplary embodimentsare also amenable to other like applications.

BACKGROUND OF THE INVENTION

Flange bolt torquing is an ongoing maintenance issue for companies thatutilize a great deal of piping. Piping systems, such as used in chemicalprocessing companies or similar, include a variety of overhead pipingand insulated/lined piping which are subject to thermal cyclingconditions. Typical flange bolt torquing for such piping systemsincludes flat washers on both sides of the pipe flange connection.Tightening the flange bolts usually requires a calibrated torque wrenchin order to apply the specified bolt torques (i.e., ft.-lbs. of torque).When anti-seize compounds are used, the torque values can be different.The tightening of the flange bolts with a torque wrench is usually donein a “crisscross” pattern that alternately tightens the bolts located180° apart. Using this pattern, the bolts are tightened in some percentincrement of the desired final bolt torque (i.e., ft.-lbs. of torque)until a majority of the final bolt torque has been achieved. Fortightening to the final torque values, the bolts are then sequentiallytightened in a clockwise fashion once around the flange. This is done toensure that the bolts are evenly stressed. Care must be taken to avoidover-torquing, which can cause damage to any plastic sealing surfaces,liners, plastic flares, and/or plastic faces.

Typically a re-torquing of the bolts is applied a minimum of twenty fourhours after the initial torque or after the first thermal cycle. Thisre-torquing allows for seating of the plastic liners and flares and forrelaxation of the bolts. Torquing typically is only done on the systemin an ambient, cooled state, and typically never while the process is atelevated temperature.

After the initial torque and re-torque of the bolts, a hydro test can beperformed following ANSI requirements. Annual re-torquing is usuallydone thereafter, especially if the process lines experience elevatedtemperatures or extreme ambient temperature situations. Again, annualre-torquing is typically only done on the system in the ambient orcooled state.

Due to the possibility of mechanical damage to polytetrafluoroethylene(PTFE) flares and/or PTFE-lined piping products, or similar, Bellevillesprings or disc springs are usually not recommended in the existingflange bolt torquing systems utilized heretofore. Prior art referencesdo not recommend the use of Belleville springs or disc springs for usewith PTFE-lined products.

The carrier can optionally include one or more through holesspaced around a circumference. The carrier includes one or more springsvertically positioned or stacked within one or more of the throughholes. When a plurality of springs is used, each of the springs canoptionally be aligned in a vertical arrangement for receiving a bolttherethrough. One or more springs can be non-coplanar with the carrierin a pre-torque orientation. The one or more springs can be coplanarwith the carrier in the loaded and torqued orientation. Aligning the oneor more springs coplanar with the carrier can be used to indicate propertorque force.

DETAILED DESCRIPTION OF NON-LIMITING EMBODIMENTS OF THE INVENTION

Referring now to the drawings wherein the showing is for the purpose ofillustrating non-limiting embodiments of the invention only and not forthe purpose of limiting the same, there is illustrated in FIGS. 1-19non-limiting examples of a torque retention arrangement in accordancewith the present invention. The invention is directed to a device thatreduces or eliminates the need to re-torque bolt systems. The torqueretention arrangement is particularly applicable to maintaining thetorque on the flanges of connecting pipe sections and will be describedwith particular reference thereto.

Several non-limiting goals and advantages of the torque retentionarrangement of the present invention are disclosed hereinafter. For allnon-limiting arrangements illustrated in FIGS. 1-19, one of the goals ofthe torque retention arrangement is to retain the desired torque (i.e.,ft.-lbs. of torque) of a bolt connecting, securing, or retention system.

Referring now to FIGS. 1-4, there is illustrated a non-limitingconfiguration of the torque retention arrangement of the presentinvention. The torque retention arrangement 10 has a monolithicconfiguration and includes the use of a carrier or cartridge 12inclusive of a spring arrangements 20, 22, 24, 26. The carrier orcartridge 12 is illustrated as having four spring arrangements; however,it will be appreciated that the carrier or cartridge can includes 1, 2or 3 spring arrangements or more than 4 spring arrangements. The carrier12 can be formed of any type of material or material combinations (e.g.,plastic, metal, ceramic, fabric, composite material, wood, etc.). Thecarrier 12 can be formed of a material having certain physicalproperties. The shape, size, configuration and thickness of the carrier12 are non-limiting. In one non-limiting configuration, the carrier isformed of a plastic material. As illustrated in FIGS. 1 and 2, thecarrier 12 has a generally circular outer perimeter 14, a generallycircular central opening 16 and a generally circular flange 18. Thethickness of the carrier is generally uniform; however, this is notrequired. The flange 18 is illustrated as including four openings,bores, apertures, or spring holes 30, 32, 34, 36, each including asingle spring arrangement 20, 22, 24, 26. As can be appreciated, thecarrier can include more than four openings, bores, apertures, or springholes or less than four openings, bores, apertures, or spring holes. Thecentral opening is generally sized to fit about an outer diameter of apipe. The openings, bores, apertures, or spring holes in the carrier aretypically oriented in the carrier to correspond to opening in the pipeflanges. The size and shape of the openings, bores, apertures, or springholes on the carrier are generally the same; however, it can beappreciated that one or more of the openings, bores, apertures, orspring holes can have a different size and/or shape from one or moreother openings, bores, apertures, or spring holes. As illustrated inFIG. 2, the openings, bores, apertures, or spring holes are equi-spacedaround a circumference of the carrier from adjacently positionedopenings, bores, apertures, or spring holes; however, this is notrequired. The openings, bores, apertures, or spring holes are alsoillustrated in FIG. 2 to be spaced an equal distance from the outerperimeter of the carrier; however, this is not required. As illustratedin FIG. 2, the openings, bores, apertures, or spring holes are spacedfrom the outer perimeter of the carrier and also spaced from the edge ofcentral opening 16 of the carrier; however, this is not required.Likewise, the spring arrangements that are positioned in openings,bores, apertures, or spring holes are spaced from the outer perimeter ofthe carrier and also spaced from the edge of central opening 16 of thecarrier; however, this is not required. In one non-limiting arrangement,the spring arrangements that are positioned in openings, bores,apertures, or spring holes such that the spring arrangement are spacedan equal distance from the outer perimeter of the carrier and the edgeof central opening 16 of the carrier.

The spring arrangement 22 is partially illustrated (FIGS. 3-4) asincluding multiple stacks of three springs (e.g., Belleville springs ordisc springs, etc.) 42, 43, 44. As can be appreciated, the springarrangement 22 can include less than three springs (one or two springs)or more than three springs in each stack. As can also be appreciated,one or more of the stacks can optionally include one or more washers(e.g., flat washer, lock washer, etc.). As can be appreciated, each ofthe spring arrangements 20, 22, 24, 26 can have the same number ofsprings; however, it can be appreciated that one or more of the springarrangement can have a different number of springs. The size, shape,thickness, material, spring strength and/or spring rating of each of thesprings in a spring arrangement that has multiple springs can be thesame or different. Also, it can be appreciated that one or more of thespring arrangement can have one or more springs having a different size,shape, thickness, material, spring strength and/or spring rating thatone or more other spring arrangements. In one non-limiting arrangement,the same number of springs and the same size, shape, thickness,material, and spring rating of the springs in each of the springarrangements used in the carrier are the same.

One or more springs in one or more of the spring arrangements includesone or more coatings (e.g., polymer coating, lubricant coating,anti-corrosion coating, anti-stick coating, Teflon® coating, plasticcoating, painted coating, etc.); however, this is not required. The oneor more coatings, when used, can inhibit or prevent a) corrosion of thesprings, b) sticking together of adjacent springs, c) impaired movementof adjacently positioned springs, d) excessive or undesired wear of thesprings, and/or e) damage to the springs.

As shown in FIG. 3, spring arrangement 22 includes three springs 42, 43,44 (e.g., disc springs, etc.) that are in a mounted and pre-loadposition. The springs 42, 43, 44 are retained within bore 32 of carrier12. Alternatively, the carrier 12 can be molded around the springarrangement such that the individual stacks of springs are securelyretained within their respective bores. In this manner, a user canmanipulate the carrier without disturbing the spring arrangement. Themounting arrangement is generally such that the springs are secured tothe carrier and cannot be removed from the carrier unless a force isexerted on the spring to force removal of the spring from the carrier orthe carrier is damage (e.g., cut, gouged, etc.) so that the springs canbe released from the carrier. As shown in FIG. 3, one exterior surfaceof the springs 22 is in a convex orientation while an opposing exteriorface is in a concave orientation. In this pre-load orientation, thestack of springs 42, 43, 44 are non-coplanar with the carrier 12.Generally, at least one of the springs includes a portion that extendsabove the top plane of surface 13 carrier 12. As illustrated in FIG. 3,a portion of springs 42 and 43 extend above the top plane of surface 13of the carrier 12. As can be appreciated, one, a plurality, or all ofthe springs can include a portion that extends above the top plane ofsurface 13 of the carrier 12. Each of the springs is illustrated asincluding a central opening to enable a rod or bolt to pass through theopening. The central opening of each of the springs generally lies in aplane that is parallel to the top plane of surface 13 of the carrier 12;however, this is not required.

As illustrated in FIG. 4, a portion of a mounting bolt 50 is insertedthrough the opening of the aligned disc springs 42, 43, 44. A nut 52 issecured to the end of the bolt. The bolt 50 is inserted sequentiallythrough a first flange 60, the spring arrangement 22, and then a secondflange 62. Upon tightening, the flanges 60, 62 are moved near each otherand the springs 42, 43, 44 are moved from a non-coplanar arrangementrelative to the carrier 12 to a planar arrangement to the carrier asillustrated in FIG. 4. As illustrated in FIG. 4, the thickness of thecarrier 12 is equal to or slightly less than the combined height orthickness of the springs 42, 43, 44 when in the compressed and loaded(torqued) orientation; however, this is not required. As such, when theinner surfaces 61, 63 of the respective flanges 60, 62 are coplanar withsurfaces 13, 15 of the carrier 12, the desired torque ft.-lbs. has beenapplied to the bolt 50 and nut 52. The material of the carrier aboutbore 32 is generally deformable to enable the springs 42, 43, 44 to movefrom a non-coplanar arrangement relative to the carrier 12 to a planararrangement to the carrier. The diameter of the circular disc springs42, 43, 44 increases as the disc springs move from a non-coplanararrangement relative to the carrier 12 to a planar arrangement to thecarrier. The ability of the carrier to deform enables the disc springsto increase in diameter without damaging the disc springs, the carrierand/or the bore of the carrier. Generally, the material of the springsand the material forming the carrier and/or the inner surface of thebore are different materials. As illustrated in FIG. 4, the threesprings are stacked on top of one another and are in contact with anadjacent spring when the springs move from a non-coplanar arrangementrelative to the carrier 12 to a planar arrangement to the carrier;however, this is not required. As illustrated in FIG. 4, the diameter ofthe carrier is less than the diameter of flanges 60, 62; however, thisis not required.

Referring now to FIG. 5-6, another non-limiting configuration of thetorque retention arrangement 10 is illustrated. The spring arrangement122 can include a plurality of individual disc springs 142, 143, 144.One or more of the disc springs 145 can be lubricated and/or coated forprotection; however, this is not required. Similar to the arrangementdescribed above, carrier 112 can include an outer perimeter 114 and aninner perimeter 116, as well as a first exterior surface 113 and asecond exterior surface 115. The materials, structure and operation ofthe carrier and spring arrangement illustrated in FIGS. 5-6 are the sameor generally the same as the carrier and spring arrangement illustratedin FIGS. 1-4, thus will not be repeated herein.

A coating arrangement on the spring 143 (i.e., lubricant coating,anti-corrosion coating, Teflon® coating, plastic coating, paintedcoating, polymer coating, anti-stick coating, flexible casing, etc.)and/or O-rings or gaskets 150, 152 on the carrier 112 can be used toprotect the spring arrangement 122 (i.e., from corrosion, sticking toone another, etc.); however, this is not required. One or more or all ofthe springs in the spring arrangement can optionally include the coatingarrangement. As illustrated in FIG. 6, only the middle spring includesthe coating arrangement. As illustrated in FIGS. 5 and 6, O-ring 150 isarranged around the spring arrangement 122 on one surface 113 of thecarrier 112. Another O-ring 152 can be applied to the other opposingsurface 115 of the carrier 112. These O-rings can be used to provideadditional sealing when flanges 60, 62 are moved near each other uponthe tightening of the nuts and bolts 50, 52 as illustrated in FIG. 4.The material used to form the O-rings is non-limiting. Generally theO-ring is formed of a compressible material.

Referring now to FIGS. 7-8, another non-limiting configuration of atorque retention arrangement 10 is illustrated. The spring arrangement222 can include a plurality of individual disc springs 242, 243, 244. Asshown, each spring can be lubricated and/or coated 262, 263, 264 forprotection. Similar to the arrangement described above regarding FIGS.1-6, carrier 212 can include an outer perimeter 214 and an innerperimeter 216, as well as a first exterior surface 213 and a secondexterior surface 215. The materials, structure and operation of thecarrier and spring arrangement illustrated in FIGS. 7-8 are the same orgenerally the same as the carrier and spring arrangement illustrated inFIGS. 1-6, thus will not be repeated herein.

The coating arrangement 262, 263, 264 on the springs 242, 243, 244(i.e., polymer coating, lubricant coating, anti-corrosion coating,anti-stick coating, Teflon® coating, plastic coating, painted coating,flexible casing, etc.) and/or O-rings or gaskets 250, 252 on the carrier212 can be used to protect the spring arrangement 222; however, this isnot required. One or more or all of the springs in the springarrangement can optionally include the coating arrangement. Asillustrated in FIG. 8, all three springs include the coatingarrangement. As shown in FIGS. 7 and 8, the O-ring 250 is arrangedaround the spring arrangement 222 on one surface 213 of the carrier 212.Another O-ring 252 can be applied to the other opposing surface 215 ofthe carrier 212. These O-rings can be used to provide additional sealingwhen flanges 60, 62 are moved near each other upon the tightening of thenuts and bolts 50, 52 as illustrated in FIG. 4. The O-rings illustratedin FIGS. 7-8 have a polygonal cross-sectional shape (e.g., square,rectangular, etc.) and the O-rings illustrated in FIGS. 5-6 have acircular or oval cross-sectional shape. The top and bottom surfaces 213,215 of the carrier includes an O-ring slot such that only a portion ofthe O-ring is positioned within the O-ring slot. A similar O-ring slotarrangement is illustrated in FIGS. 5-6. The O-ring slot is designed toposition and optionally retain the O-ring in the O-ring slot. The shapeof the O-ring slot is non-limiting. As illustrated in FIGS. 5-8, aportion of the O-ring extends over the top and bottom surfaces of thecarrier such that when flanges 60, 62 are moved near each other upon thetightening of the nuts and bolts 50, 52 as illustrated in FIG. 4, theO-rings are compressed between the carrier and the adjacently positionedflange.

Referring now to FIG. 9, another non-limiting configuration of thetorque retention arrangement 10 is illustrated. The spring arrangement322 can include a plurality of individual disc springs 342, 343, 344. Asshown in FIG. 9, the stacked arrangement of springs 322 can include acoating 362 around the entire stacked arrangement 322. This coating 362can be a wrapping or a dipping of the stacked springs 322. Such acoating can optionally be a similar coating material as described above.Additionally or alternatively, the coating 362 can be a wrapping ofplastic or a foil to secure and hold the stacked springs 322 in apackaged arrangement. The materials, structure and operation of thecarrier and spring arrangement illustrated in FIG. 9 are the same orgenerally the same as the carrier and spring arrangement illustrated inFIGS. 1-8, thus will not be repeated herein. FIG. 9 does not illustratethe use of one or more O-rings; however, it will be appreciated that thetorque retention arrangement illustrated in FIG. 9 could optionallyinclude one or more O-rings and a modified carrier having one or moreO-ring slots as illustrated in FIGS. 5-8. Likewise, the torque retentionarrangement illustrated in FIGS. 1-4 can optionally include one or moreO-rings and the modified carrier having one or more O-ring slots (asillustrated in FIGS. 5-8), and/or a coating arrangement on one or moreof the springs (as illustrated in FIGS. 5-9).

Referring now to FIG. 10, another non-limiting configuration of thetorque retention arrangement 10 is illustrated. The carrier 412 istherein shown with a shim or flap plate 414 adjacent the lower end ofthe bore 432. It is to be appreciated that when a bolt and nut aretorqued, the lowest edge of disc spring 444 could dig into the lowerpart of the bore 432. The shim or flap plate 414 provides a surface forthe lower edge of disc spring 444 to slide across. In this arrangement,the lower edge of the bottom disc spring 444 will not scrape against theunderlying flange surface during the torquing operation. The shape,thickness and material used to form the flap plate are non-limiting(e.g., metal, plastic, composite material, ceramic material, etc.). Asillustrated in FIG. 10, the flap plate is spaced inwardly from the planeof bottom surface 415 of the carrier 412. As can be appreciated, flapplate 414 can be positioned even with the plane of bottom surface 415 ofthe carrier 412. Carrier 412 includes a plate slot 416 that is used tosecure the flap plate to the carrier. The plate slot is illustrated asspaced inwardly from the plane of bottom surface 415 of the carrier 412.The flap plate is generally sized such that it was a width W that isless than 40% the width or diameter of bore 432, and generally less than30% the width or diameter of bore 432, and typically less than 20% thewidth or diameter of bore 432, and more typically less than 15% thewidth or diameter of bore 432 (e.g., 10% the width or diameter of thebore, etc.). The thickness of the flap plate is generally less than thethickness of one or all of the springs; however, this is not required.As illustrated in FIG. 10, spring 444 contacts the top surface of flapplate 414 prior to the compression of the spring; however, this is notrequired. The materials, structure and operation of the carrier andspring arrangement illustrated in FIG. 10 are the same or generally thesame as the carrier and spring arrangement illustrated in FIGS. 1-9,thus will not be repeated herein. FIG. 10 does not illustrate the use ofone or more O-rings; however, it will be appreciated that the torqueretention arrangement illustrated in FIG. 10 could optionally includeone or more O-rings and a modified carrier having one or more O-ringslots (as illustrated in FIGS. 5-8) and/or a coating arrangement on oneor more of the springs (as illustrated in FIGS. 5-9). As can also beappreciated, the flap plate and plate slot arrangements illustrated inFIG. 10 can optionally be used in the torque retention arrangementsillustrated in FIGS. 1-9.

Referring now to FIGS. 11-12, another non-limiting configuration of thetorque retention arrangement 10 is illustrated. The spring arrangement522 can include a seal 523 around the interior of the associated bore532. The shape, size and material of the seal are non-limiting. The sealis generally formed of a compressible and deformable material. In oneexemplary example, the seal 523 can be a rubber seal, plastic seal,polymer seal, etc. that initially helps to secure the disc springs 542,543, 544 in place, and upon torquing a mounting bolt 550 and nut 552between the respective flanges 560, 562, the disc springs 542, 543, 544compress against the seal 523 to keep out any foreign materials fromgetting into the bore 532 and between the disc springs 542, 543, 544. Asillustrated in FIGS. 11-12, the shape of the seal changes when thesprings are compressed when flanges 560, 562 are moved near each otherupon the tightening of the nut and bolt 550, 552 as illustrated in FIG.12. As illustrated in FIGS. 11-12, the wall of the bore 532 isnon-planar and includes one or more angle surfaces and angle away fromthe center of the bore; however, this is not required. These anglessurfaces enable the seal to properly deform and to allow the springs tobecome planar when flanges 560, 562 are moved near each other upon thetightening of the nut and bolt 550, 552 as illustrated in FIG. 12.Generally, the material used to form the seal is different from thematerial used to form the carrier. Typically, the material of thecarrier is a harder, less deformable material than the material used forthe seal; however, this is not required. The seal can be frictionallyconnected to the carrier or connected by other or additional means(e.g., adhesive, melt bond, etc.). As illustrated in FIG. 11, a portionof the seal optionally extends above and/or below surfaces 513, 515prior to the compression of the springs, but not after the compressionof the springs (as illustrated in FIG. 12). The materials, structure andoperation of the carrier and spring arrangement illustrated in FIGS.11-12 are the same or generally the same as the carrier and springarrangement illustrated in FIGS. 1-10, thus will not be repeated herein.FIGS. 11-12 do not illustrate the use of one or more O-rings; however,it will be appreciated that the torque retention arrangement illustratedin FIGS. 11-12 could optionally include one or more O-rings and amodified carrier having one or more O-ring slots (as illustrated inFIGS. 5-8) and/or a coating arrangement on one or more of the springs(as illustrated in FIGS. 5-9). As can also be appreciated, the flapplate and plate slot arrangements illustrated in FIG. 10 can optionallybe used in the torque retention arrangements illustrated in FIGS. 11-12.

Referring now to FIGS. 13-15, another non-limiting configuration of thetorque retention arrangement 10 is illustrated. The spring arrangement622 therein illustrated includes a series of three disc springs 642,643, 644 and a seal lining 623 within the bore 632. As shown, the wallsof the bore 632 are not planar. The non-planar walls of the bore 632provide an area for the seal lining 623 to expand and bend when thetorque flange connector 610 is secured with a nut 652 and bolt 650 tothe extent of flattening the disc springs 642, 643, 644 into a co-planararrangement with the carrier 612 as illustrated in FIG. 15. The seallining 623 can be frictionally connected to the carrier or connected byother or additional means (e.g., adhesive, melt bond, etc.). Generally,the material used to form the seal liner is different from the materialused to form the carrier. Typically, the material of the carrier is aharder, less deformable material than the material used for the sealliner; however, this is not required.

As illustrated in FIG. 14, a portion of the seal liner optionallyextends above and/or below surfaces 613, 615 prior to the compression ofthe springs, but not after the compression of the springs (asillustrated in FIG. 15). The materials, structure and operation of thecarrier and spring arrangement illustrated in FIGS. 13-15 are the sameor generally the same as the carrier and spring arrangement illustratedin FIGS. 1-12, thus will not be repeated herein. FIGS. 13-15 do notillustrate the use of one or more O-rings; however, it will beappreciated that the torque retention arrangement illustrated in FIGS.13-15 could optionally include one or more O-rings and a modifiedcarrier having one or more O-ring slots (as illustrated in FIGS. 5-8)and/or a coating arrangement on one or more of the springs (asillustrated in FIGS. 5-9). As can also be appreciated, the flap plateand plate slot arrangements illustrated in FIG. 10 can optionally beused in the torque retention arrangements illustrated in FIGS. 13-15. Asalso can be appreciated, the seal illustrated in FIGS. 11-12 couldoptionally be used in the torque retention arrangement of FIGS. 13-15.As can also be appreciated, the seal liner illustrated in FIGS. 13-15could optionally be used in the torque retention arrangement of FIGS.1-12.

Referring to FIGS. 16-19, additional non-limiting configurations of thetorque retention arrangement 10 are illustrated. As illustrated in FIGS.16 and 18, the carrier includes a side slot, opening or gap. Such anarrangement can be used to enable the torque retention arrangement to beslipped about the pipe liner positioned between the pipe flanges withouthaving to fully separate the pipes. This can provide a significantadvantage in time and can reduce the complexity of having to insert andreplace the torque retention arrangements of the present invention onexisting pipe systems. A gap 701, 801 in the carrier 712, 812illustrated in FIGS. 16 and 18 allows the entire monolithic retentionarrangement 710, 810 to be installed onto the pipe at any stage in theassembly process in the same fashion as a snap ring, thereby eliminatingthe need for the monolithic product 710, 810 to be stacked in aparticular order. This particular arrangement is particularly beneficialin situations where the torque retention arrangement is used as aretrofit device. The entire flange/fitting assembly, including anyplastic seal (e.g., PTFE seal, etc.), can remain intact while thefasteners and the torque retention arrangement are installed.

Referring now to FIGS. 16-17, there is illustrated a single-pieceflexible material (i.e., metallic, plastic, composite material) formingcarrier 712. Positioned in the carrier is a plurality of grommets 713.The carrier includes a plurality of openings that each includes agrommet. The number of grommets on the carrier is non-limiting. Thedistance between adjacently positioned grommets about the perimeter ofthe carrier is generally the same; however, this is not required.Grommets 713 can be used to hold the springs 742, 743, 744, 745 to thecarrier 712 and provide sealing and visual cues to the subsequent springcompression. The grommets can be formed of any type of material (e.g.,plastic, metal, composite material, etc.). The thickness of the grommets713 provides the desired visual cues to the achieved post-load andtorqued orientation for the torque retention arrangement. Four springsare illustrated in the grommet; however, it can be appreciated that lessthan four or more than four springs can be included in one or more orall of the grommets.

The carrier 712 can comprise a thin flat piece of material that retainsthe grommet 713 for retention of the spring arrangement 722. As shown,the spring arrangement 722 includes four springs 742, 743, 744, 745stacked in a vertical arrangement. It is to be appreciated that anynumber of plurality of springs can be used in the aforementionedarrangement. Grommet 713 has a generally cylindrical shape; however,this is not require. Each of the grommets is generally the same size andshape; however, this is not required. The grommet is generally formed ofa different material from the carrier; however, this is not required.The grommet includes an internal cavity wherein the springs are located.The springs can be connected to the grommet by any means. As illustratedin FIG. 17, the exterior surface of the grommet includes a carrier slot703 that is designed to receive a portion of the carrier such that thegrommet can be secured to the carrier. Generally, the carrier slot ispositioned at the mid-point of the longitudinal axis of the grommet asillustrated in FIG. 17; however, this is not required. The thickness ofthe carrier is generally less than the longitudinal length of thegrommet; however, this is not required. In one non-limiting arrangement,the thickness of the carrier is generally less than 70% the longitudinallength of the grommet, typically the thickness of the carrier is lessthan 50% the longitudinal length of the grommet, more typically thethickness of the carrier is less than 40% the longitudinal length of thegrommet, still more typically the thickness of the carrier is less than25% the longitudinal length of the grommet, a yet more typically thethickness of the carrier is less than 10% the longitudinal length of thegrommet. The longitudinal length of the grommet is equal to or slightlyless than the combined height or thickness of the stacked springs whenin the compressed and loaded (torqued) orientation; however, this is notrequired. The materials, structure and operation of the springarrangement illustrated in FIGS. 16-17 are the same or generally thesame as the carrier and spring arrangement illustrated in FIGS. 1-15,thus will not be repeated herein. FIGS. 16-17 do not illustrate the useof one or more O-rings about one or more grommets; however, it will beappreciated that the torque retention arrangement illustrated in FIGS.16-17 could optionally include one or more O-rings and a modifiedgrommet having one or more O-ring slots (as illustrated in FIGS. 5-8)and/or a coating arrangement on one or more of the springs (asillustrated in FIGS. 5-9). As can also be appreciated, the flap plateand plate slot arrangements illustrated in FIG. 10 can optionally beused in the grommets illustrated in FIGS. 16-17. As also can beappreciated, the seal illustrated in FIGS. 11-12 could optionally beused in the grommets illustrated in FIGS. 16-17. As can also beappreciated, the seal liner illustrated in FIGS. 13-15 could optionallybe used in the grommets illustrated in FIGS. 16-17.

As shown in FIGS. 18 and 19, the torque retention arrangement 10 caninclude a carrier 812 with a plurality of fingers 813, 814, 815, 816extending therefrom. The fingers 813, 814, 815, 816 can each include abore hole therethrough for mounting the spring arrangement 822 therein.The number of fingers in the carrier is non-limiting. Generally, thecarrier includes a plurality of fingers. As described above, theplurality of springs 842, 843, 844 can be aligned in a verticalarrangement and be retained within the respective bore holes. Asillustrated in FIG. 18, the longitudinal length of the fingers isgreater than the width of the portion of the carrier between thefingers; however, this is not required. In one non-limiting arrangement,the smallest width of the portion of the carrier between the fingers isgenerally less than 70% the longitudinal length of the fingers,typically, the smallest width of the portion of the carrier between thefingers is generally less than 50% the longitudinal length of thefingers, and more typically the smallest width of the portion of thecarrier between the fingers is generally less than 30% the longitudinallength of the fingers.

As illustrated in FIG. 18, the portion of the carrier between twofingers has a generally constant width and has an arcuate shape;however, this is not required. The spring arrangement 822 is illustratedin FIG. 18 as being located closer, but spaced from, the end of thefinger than the bottom of the finger; however, this is not required. Thefront end of each of the fingers is generally arcuate shaped; however,this is not required. The thickness of the fingers at the location ofthe stacked springs is equal to or slightly less than the combinedheight or thickness of the stacked springs when in the compressed andloaded (torqued) orientation; however, this is not required. Thematerials, structure and operation of the spring arrangement illustratedin FIGS. 18-19 are the same or generally the same as the carrier andspring arrangement illustrated in FIGS. 1-15, thus will not be repeatedherein. FIGS. 18-19 do not illustrate the use of one or more O-rings;however, it will be appreciated that the torque retention arrangementillustrated in FIGS. 18-19 could optionally include one or more O-ringsand a modified carrier having one or more O-ring slots (as illustratedin FIGS. 5-8) and/or a coating arrangement on one or more of the springs(as illustrated in FIGS. 5-9). As can also be appreciated, the flapplate and plate slot arrangements illustrated in FIG. 10 can optionallybe used in the fingers of the carrier illustrated in FIGS. 18-19. Asalso can be appreciated, the seal illustrated in FIGS. 11-12 couldoptionally be used in the fingers of the carrier illustrated in FIGS.18-19. As can also be appreciated, the seal liner illustrated in FIGS.13-15 could optionally be used in the fingers of the carrier asillustrated in FIGS. 18-19.

It is to be appreciated that the open area (i.e., discontinuouscircumferential shape) in the carrier 712, 812 shown in FIGS. 16 and 18,allows the carrier 712, 812 to fit about an existing system such as, butnot limited to, an existing pipe system. The carrier can be designed tobe positioned between the flanges of two pipe sections. Alternatively,the carrier can be positioned about a pipe section and adjacent to thepipe section flange such that the carrier is not positioned between theflanges of two pipe sections. In such an arrangement, the pipe sectionneed not be separated to use the torque retention arrangement of thepresent invention. The carrier of the torque retention arrangement cansimply be placed about one of the pipe section while the flanges of thetwo pipe sections remain positioned together. The connectors used toconnect the two flanges together (e.g., bolt and nut, screw, etc.) arepassed through the openings in the flanges and through the spring holesin the torque retention arrangement and then tightened. Thisconfiguration of the torque retention arrangement can be used to easilyand conveniently use the torque retention arrangement on existing pipesystems without having to take apart the pipe sections and separatingthe flanges of the pipe sections.

The carriers described herein can be formed of metal or plasticmaterials. The spring arrangements are described as a plurality ofsprings. The spring arrangements as shown include three or four springsin each stack; however, other numbers of springs can be used. The springstacks can be snapped into the carrier; however, other retentionarrangements can be used (e.g., adhesive, melted bond, solder, weldbead, hook and loop fastener, fiction fit, etc.).

The carrier and spring stacks as shown in the figures comprise amonolithic body. It is to be appreciated that the spring action of thedisc springs are concentrated under each bolt. The thickness of thecarrier provides for a desired visual cue to achieve the recommendedtorque in ft.-lbs. The material of the carrier can be produced to meetthe necessary chemical resistance and operating temperatures of thepiping system and flange connectors.

As described above, the disc springs can be coated with an anti-gallant,lubricant, or anti-corrosion coating to further improve fastener torqueaccuracy. Additionally, the fastener stack can be protected from thepipe contents, namely, exposure of the pipe contents by theincorporation of O-rings, gaskets around each spring stack, individuallyprotected springs, protection around the entire stack, the carrierpartially encasing the disc spring outer diameters, and/or a bottom sealmolded into the carrier surrounding each spring stack out of plane. Allof the aforementioned protections of the fastener stack enablescompression in order to seal when torqued.

It is to be appreciated that the torque flange connector is generally amonolithic body that is resistant to chemicals and temperatures.

It will thus be seen that the objects set forth above, among those madeapparent from the preceding description, are efficiently attained, andsince certain changes may be made in the constructions set forth withoutdeparting from the spirit and scope of the invention, it is intendedthat all matter contained in the above description and shown in theaccompanying drawings shall be interpreted as illustrative and not in alimiting sense.
